rrvo'rAL snsn MOUNTING.

Application filed May 10, 1921, Serial No. 488,288. Renewed September 4, 1924.

My invention relates to pivotal sash mountings and to hanger elements adapted for use in pivotally united pairs as hangers for mounting sashes in window frames, more especially for mounting pivoted ventilators in metallic sashes of a type which are to be permanently and immovably set in window apertures of buildings.

One aim of my invention is to standardize such'hanger elements, so as to render them readily interchangeable, and capable, with equal facility, of being attached to the movable and immovable sections of the window structure.

Another object of my invention is to entend the scope of utility of such sash mounting appurtenances by enabling them to serve as weathering strips for overlapping the junctures between the sides of the pivoted sashes or ventilators and their frames or mountings when the sashes are in closed position. Or, to state the matter differently, my invention makes it possible to utilise the weathering itself forpivotally mounting a sash.

Other objects and attendant advantages of my invention will become readily apparent from the detailed description which follows:

In the drawings Fig. I is a perspective view of the exterior side of a typical metallic window sash provided with a pivoted ventilator, showing the manner in which hanger elements of my invention are applied.

Fig. 11 is a fragmentary view on an enlarged scale showing the details of one of the ventilator pivots.

Fig. 111 is an illu *tration similar to II showing the ventilator of the window in open position.

Fig. TV is a crosssec'tional view through one of the pivot axes of the ventilaton the lane of the section being indicated by the line TV-IV in Fig. H.

Fig. V is adetail sectional view across the line of juncture of the ventilator and its framing taken above the axis of pivoting suggested by the arrows VV in Fig. I, the ventilator being shown slightly open so as to avoid confusion as between the movable and immovable portions of the window sash.

Fig. V1 is a view similar to Fig. V at a level below the pivot axis.

Fig, V11 is a detail perspective view show ing clearly the construction of the pivot end of one of the hanger elements.

Fig. VIII is a perspective view of one of the special washers in the pivot joints shown.

Fig. IX is a fragmentary perspective view showing, to better advantage, the details of the sash pivot and the function of the special washers; and

Fig. X is an illustration generally similar to Fig. IX, but slightly modified in some details so that certain features of my invention may 1 be more readily understood by comparison.

Referring'first to Fig. VII ofv the draw ings, it will be observed that the hanger element or weathering member shown is in the form of a channel bar comprehensively indicated at 1 having weathering flanges 2 and 8 which are joined by a uniting web 4. Said bar may be constructed as a sheet metal stamping, bent to the form shown by pressing or in any other approved manner. A

portion of the wider flange 3 at the end of the bar is turned laterally to produce an integral projection 5 which is to serve as a pivot ear. Said pivot ear is oiiset somewhat from the plane of the web 4 as clearly shown, for a purpose which will become obvious from further description, and provided with an aperture 6 for the accommodation of a suitable pivot bolt. The web i of the channel bar is continued so as to be co-extensive with the pivot ear 5, and preferably rounded as indicated at 7 Holes such as shown at 8 are provided at intervals along the length of the bar for the reception of appropriate rivets whereby attachment to the window sash sections may be effected. The narrower flange 2 of the channel is prolonged to form a tongue 9 which is divided from the web 4 by an incision 10. The elements 1 are, in practice, made in difierent lengths depending upon the proportions of the sashes which are to be hung.

As an example illustrative'of the application of my invention in practice I have shown in Fig. I a metallic window sash S manufactured of standard cross sectional shapes, and of a type intended to be permanently and immovably set in a window aperture of a building. Certain of the inuntins and mullions M of the sash are interrupted. as shown to afford a window openinggflor frame in which a separate pivoted ventilator sash V is .uiiounted. In hanging such a ventilator I employ vateach side. a pair of hanger elements one of my in- 5 vention. One of said elements is fastened to the lower half of the portion of the mnllion which borders the opening O, and the other or companion element, 18 attached to the upper half of the perimetrical member P or the sash. As here shoivn,thehanger members taehment to the ventil 2O rivets 12 asshovvn in Fig. V.

tor- V is closed, thus ati'ording a double weathering or .seal which prevents passage of air or rain water. The companion hanger element 1-attac'hedto the lower half of the portion of i'llCrDlUlliOIl ,M ofthestationary sash S which borders the side of the opening OZsee I, issecured in precisely the same manner as described above, .-rivets 15 being likeivise employed in ett'eeting attachment. The relation of the conta'eting parts is, llOWGVBl', here reversed, the

flanges-2 and 3 ot'the'barcooperatingin thisinstanoe with theshoulcler ltScand .vveb 17 ofthe periinetrical Ineinber fP of the ventilator. The reversed arrangement, in the PEItltlOIlnElbOVG noted, of the two C0111- plernentary hanger elements 1, 1 constituting the pivot mounting at-each side ofithe ventilator is necessary in order to permit swinging ofthelatterwas Will be clearl i ehvious 1'011111 cursory exan'iination oil -I. After the hanger elementalare properly ,seeuredto the members of the.Windowsash structure, the ,or-ganizati on is .assenibledixvith IllG'lZllLEltlll'Qd ears in sash .and vtraine overlapping and pivot=bo1ts 18 are passed through the registering ears of lthe respective hangereeleinents as suggested in cross section in Fig. IV.

.Inthe course. ofassemhling, I preferably interpose in the hinge joints between the eaten-13, special -spacin teshersssuch as show'net l9inil igs. IVancl VIII, similar in ontline to the ears. These Washers have .-.straight, perpendicularly (turned portions 20,- vihichare adapted to engage behindthe .oil'set shoulders of the ea rs 5 so as to preventrelative irotation when the ventilator is operated.

F-ronrF IX, it will be, particularly -loted that the special washers 19-19 correspond tin and providedat mieend in shape to the pivotears i3.5 so as to he capalj le oihcompletelv lillinglho gap between them when the pivoted sash or ventilator is in closed position: thus preventing ingress of air and water thl'o h the pivot joint. This "feature \i'ill pr inns: it best understood by reference to "3-; Where I haveshoivn, for the purposes of compari n, ordinary disk washers IV-Al in- .ncad of;specialm'ashcr: 1 1%). in this instance, it will be seen that the gap (2" is onl; partially closed, thus leaving quite a large opening vvvhich is entirely unprotected.
